FIG. 3 is a cross-sectional perspective view of a main part showing the pouch container package C1 with a spout. FIG. 4 is a plan view of relevant parts showing the pouch container package C1 with a spout. FIG. 5 is a sectional view taken along line VV of FIG. FIG. 6 is a sectional view taken along the line VI-VI in FIG. 3 and 4, a packaging material 9 described later is omitted for convenience of understanding. 4 to 6, the cap 7 is omitted for convenience of understanding. Note that the z direction in the figure corresponds to the axial direction of the present invention. Also, one side in the z direction may be referred to as an upper side, and the other side may be referred to as a lower side.

  As shown in FIGS. 1 and 2, the pouch container B has a spout 8 and a packaging material 9.

  The packaging material 9 includes a pair of exterior sheets 91, a top sheet 92, and a bottom gusset sheet 93. A pair of side seals 94, a top seal 95, and a bottom seal 96 are formed. It is configured to be self-supporting in a state where S is filled. The shape and film configuration of the packaging material 9 are not particularly limited, and the configuration described below is an example of the packaging material 9.

  The pair of exterior sheets 91 overlap in the y direction. The shape and size of the pair of exterior sheets 91 are not particularly limited, and in the present embodiment, they are substantially rectangular as a whole. The bottom gusset sheet 93 is located near the lower end in the z direction of the pair of exterior sheets 91, and serves to form the bottom of the packaging material 9. The top sheet 92 is located near the upper end in the z direction of the pair of exterior sheets 91 and is sandwiched between the pair of exterior sheets 91. A hole for inserting the spout 8 is formed in the top sheet 92.

  The pair of exterior sheets 91, the top sheet 92, and the bottom gusset sheet 93 are usually made of a resin film. The resin film is required to have basic performance as a package, such as impact resistance, abrasion resistance, and heat resistance. Further, since the pair of side seal portions 94, the top seal portion 95, and the bottom seal portion 96 are generally formed by heat sealing, the sheet is also required to have heat sealability. As the sheet, a multi-layer sheet having a base film layer and a sealant layer for imparting heat sealability is preferable, and when high gas barrier properties or light-shielding properties are required, the base film layer and the sealant layer may be used. It is preferable to provide a barrier layer between them. In addition, you may provide a barrier property to a base film layer itself. In this case, a multilayer sheet having a barrier layer and a sealant layer is obtained by using the barrier layer as a base film layer.

  Here, constituent materials of the base film layer, the sealant layer, and the gas barrier layer are exemplified. The lamination of each of these layers can be performed by a conventional lamination method, for example, co-extrusion lamination, dry lamination with an adhesive, thermal lamination in which a thermo-adhesive layer is sandwiched and thermally bonded, or the like.

  Examples of the film constituting the base film layer include polyester (polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polybutylene terephthalate (PBT), polycarbonate (PC), etc.), polyolefin (polyethylene (PE), polypropylene ( PP), polyamide (nylon-6, nylon-66, etc.), polyacrylonitrile (PAN), polyimide (PI), polyvinyl chloride (PVC), polyvinylidene chloride (PVDC), polymethyl methacrylate (PMMA), poly An example is a stretched or unstretched film composed of one or more layers composed of ether sulfone (PES) or the like.

  Examples of the film constituting the sealant layer include low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), ethylene-propylene copolymer (EP), unstretched polypropylene (CPP), and biaxially stretched nylon (ON). , Ethylene-olefin copolymer, ethylene-acrylic acid copolymer (EAA), ethylene-methacrylic acid copolymer (EMAA), ethylene-vinyl acetate copolymer (EVA), etc. Or an unstretched film of

  As the gas barrier layer, a metal thin film such as aluminum, a resin film such as vinylidene chloride (PVDC) or ethylene-vinyl alcohol copolymer (EVOH), or an arbitrary synthetic resin film (for example, a base film layer may be used). ) Can be exemplified by a film obtained by vapor deposition (or sputtering) of an inorganic oxide such as aluminum, aluminum oxide or silica.

  The pair of side seal portions 94 are portions where both ends in the x direction of the pair of exterior sheets 91 are joined. The top seal portion 95 is a portion where the upper ends in the z direction of the pair of exterior sheets 91 and both ends in the y direction of the top sheet 92 are joined. The bottom seal portion 96 is a portion where a portion near the lower end in the z direction of the pair of exterior sheets 91 and the bottom gusset sheet 93 are joined.

  The spout 8 is for filling the contents S in the pouch container B or for discharging the contents S from the pouch container B. In the illustrated example, the spout 8 is disposed between the pair of exterior sheets 91. The configuration of the spout 8 is not particularly limited, and has a tubular portion 81 and a flange portion 82 in the present embodiment.

  The cylindrical portion 81 is a portion through which the contents S to be filled and extracted pass. In the illustrated example, a screw portion 811 is formed in the cylindrical portion 81. The screw portion 811 is used for detachably attaching the replacement spout A1 to the spout 8, and has a female screw structure, for example. In the illustrated example, a first flange portion 812 is formed in the cylindrical portion 81. The first flange portion 812 is provided at a distance below the screw portion 811 in the z direction, and is a ring-shaped portion when viewed in the z direction. In the illustrated example, the distal end surface 81a of the tubular portion 81 is perpendicular to the z direction, and the positions of the components in the z direction are the same, but the present invention is not limited to this.

  The flange portion 82 is a portion extending along the xy plane from the lower end in the z direction of the cylindrical portion 81, and in the illustrated example, has a ring shape when viewed in the z direction. The material of the spout 8 is not particularly limited, but when forming a spout seal portion 97 described later, the spout 8 is made of a resin having heat sealing properties.

  The cylindrical portion 81 of the spout 8 is inserted through a hole provided in the top sheet 92, for example, from below in the z direction and upward. Further, as shown in FIGS. 1, 5 and 6, the spout seal portion 97 is formed by heat-sealing the flange portion 82 and the top sheet 92. Thereby, the spout 8 is attached to the packaging material 9 in an airtight state.

  The contents S are contained in a pouch container B. The contents S are liquid objects having fluidity such as liquids and gel-like objects. The type of the contents S is not particularly limited, and examples thereof include daily necessities such as detergents, pharmaceuticals, and food and drinks.

  The replacement spout A1 is detachably attached to the spout 8 of the pouch container B. The replacement spout A1 of the present embodiment has a main body 1. The replacement spout A1 further includes a cap 7. Note that the replacement spout of the present invention is not necessarily limited to the configuration having the cap 7, and in the following description, a case where the cap 7 is provided as a preferred embodiment, for example, from the viewpoint of performing measurement will be described.

  The main body 1 is a portion that is detachably attached to the cylindrical portion 81 of the spout 8 of the pouch container B. The material of the main body 1 is not particularly limited, and is made of, for example, a polypropylene (PP) resin. In addition, in order to reduce the content S remaining in the main body 1, the main body 1 is formed using a water-repellent material, or fine irregularities are formed on the mold side, so that the main body 1 has a water-repellent effect. Water repellency may be imparted to the main body 1 by applying a water-repellent coating to the main body 1. The main body 1 has a pouring nozzle 2, a liquid receiving part 3, a fixing part 4, and a cover part 6.

  The liquid receiving part 3 is a part that functions to receive the contents S remaining in the cap 7 and return the contents S into the pouch container B, for example. The liquid receiving part 3 has a wall part 31 and a bottom part 32.

  The wall 31 has a cylindrical shape whose axial direction is the z direction. The wall portion 31 has a size that is located outside the cylindrical portion 81 of the spout 8 when viewed in the z direction, and has a larger diameter than the cylindrical portion 81. In the illustrated example, a screw portion 311 is formed in the wall portion 31. The screw portion 311 is configured to detachably attach the cap 7 by screwing, and has a male screw structure, for example.

  The bottom 32 is connected to the lower end of the wall 31 in the z direction, and extends inward from the lower end of the wall 31 in the z direction. In the illustrated example, the bottom portion 32 has an annular shape in which a pouring hole 326 is formed near the center. The pouring hole 326 is a hole through which the contents S pass when the contents S are poured. The bottom 32 has a surface 321. The surface 321 faces the upper side in the z direction of the bottom portion 32 and is a surface located outside the pouring nozzle 2 when viewed in the z direction. Details of the surface 321 will be described later.

  The pouring nozzle 2 extends upward from the surface 321 of the bottom portion 32 in the z direction, and is a portion that forms a passage through which the contents S are discharged. The pouring nozzle 2 includes a pouring hole 326 when viewed in the axial direction z. The shape of the dispensing nozzle 2 is not particularly limited, and in the illustrated example, the dispensing nozzle 2 has an annular shape with a part cut out when viewed in the z direction. The dispensing nozzle 2 has a tip 21 and a slit 22. The tip 21 is an end of the pouring nozzle 2 on the upper side in the z direction. In the illustrated example, the tip 21 is inclined with respect to the z direction. Further, the distal end portion 21 is located above the upper end in the z direction of the wall portion 31 in the z direction. The slit 22 is a part of the pouring nozzle 2 that is partially cut out in the circumferential direction from the distal end portion 21 to the lower end of the pouring nozzle 2 in the z direction. In the illustrated example, the slit 22 has a shape along the z direction.

  The fixing part 4 is connected to the liquid receiving part 3 on the lower side (the other side) in the z direction, and is detachably attached to the spout 8 of the pouch container B. The fixing part 4 has a mounting part 41 and an insertion part 42.

  The insertion part 42 is a cylindrical part that extends downward from the pouring hole 326 of the bottom part 32 of the liquid receiving part 3 in the z direction and is inserted inside the cylindrical part 81 of the spout 8. The shape of the insertion portion 42 is not particularly limited, and in the illustrated example, the insertion portion 42 has a cylindrical shape whose axial direction is the z direction. In the present embodiment, the insertion portion 42 has a size that overlaps the pouring nozzle 2 when viewed in the z direction. Further, in this example, the inner diameter of the insertion section 42 and the inner diameter of the pouring nozzle 2 are substantially the same. In this example, the length of the insertion portion 42 in the z direction is shorter than the diameter. Other shapes of the insertion portion 42 include a single portion provided only in a part in the circumferential direction, a shape including a plurality of portions divided in the circumferential direction, and the like. When the insertion portion 42 is provided in a part in the circumferential direction as described above, it is preferable that the insertion portion 42 be provided in the direction in which the slit 22 is located. According to such a configuration, there is an advantage that the contents S that have passed through the slit 22 can be more reliably poured into the spout 8.

  The attachment portion 41 is a cylindrical portion extending downward from the bottom 32 of the liquid receiving portion 3 in the z direction and detachably attached to the cylindrical portion 81 of the spout 8 from the outside. The mounting portion 41 includes the cylindrical portion 81 and the insertion portion 42 when viewed in the z direction. In other words, the insertion portion 42 is located inside the attachment portion 41 when viewed in the axial direction z. That is, the attachment portion 41 has a larger diameter than the insertion portion 42 and the cylindrical portion 81. In the illustrated example, the mounting portion 41 has a longer dimension in the z direction than the insertion portion 42. That is, the lower end of the mounting portion 41 in the z direction is located lower than the lower end of the insertion portion 42 in the z direction. In the illustrated example, the lower end in the z direction of the mounting portion 41 is close to the first flange portion 812 of the cylindrical portion 81 of the spout 8. A screw portion 411 is formed on the mounting portion 41. The screw portion 411 is formed on the inner peripheral surface of the attachment portion 41 and is screwed with the screw portion 811 of the cylindrical portion 81 of the spout 8.

  Here, the bottom 32 has a back surface 325. The back surface 325 is one surface of a portion of the bottom portion 32 located between the insertion portion 42 and the attachment portion 41, and faces the lower side in the z direction on the opposite side to the front surface 321. The back surface 325 has an annular shape when viewed in the z direction. The back surface 325 is parallel to the distal end surface 81a of the tubular portion 81, and in the illustrated example, the back surface 325 is perpendicular to the z direction. That is, the position of each part of the back surface 325 in the z direction is the same. In the illustrated example, the back surface 325 is in contact with the entire periphery of the distal end surface 81a of the cylindrical portion 81 of the spout 8.

  The cover portion 6 is a portion that covers a mounting location between the tubular portion 81 of the spout 8 and the mounting portion 41. In the illustrated example, the cover part 6 has an outer cylinder part 61 and a connecting part 62. The outer cylinder part 61 is a cylindrical part located outside the mounting part 41 in the z direction. The connecting portion 62 of the present example has a shape whose diameter becomes larger toward the lower side in the z direction. The lower end of the outer cylinder 61 in the z direction is located lower than the lower end of the mounting part 41 in the z direction. The connection part 62 is a part that connects the upper end of the outer cylinder part 61 in the z direction and the liquid receiving part 3.

  As shown in FIGS. 3 to 6, the surface 321 of the present embodiment includes an inclined surface 322 and a groove 323. The inclined surface 322 is inclined downward in the z direction from the wall 31 of the liquid receiving part 3 toward the pouring nozzle 2. In the present embodiment, the inclined surface 322 is formed in substantially all directions of the surface 321 and has a so-called mortar shape. The groove 323 is formed inside the inclined surface 322 when viewed in the z direction, and is located between the inclined surface 322 and the ejection nozzle 2. As shown in FIG. 5, the groove 323 has a shape recessed downward in the z direction from the inclined surface 322 at least at a position where the slit 22 of the pouring nozzle 2 and the surface 321 face each other.

  Since the annular surface 321 has the inclined surface 322, the lower end 3210, which is the lower end (the other end) of the surface 321 in the z direction, has a circular shape along the pouring nozzle 2. Further, as shown in FIG. 5, the lower end 3210 is inclined such that the azimuth where the slit 22 is located in the circumferential direction is the lowest in the z direction. That is, of the lower end 3210, the first portion 321a located in the circumferential direction of the slit 22 in the circumferential direction is lower than the second portion 321b located on the opposite side to the slit 22 in the circumferential direction by the dimension z1 shown in FIG. Located in. As shown in FIG. 6, the third part 321c located between the first part 321a and the second part 321b in the circumferential direction is located between the first part 321a and the second part 321b in the z direction. doing. The first portion 321a is located below the third portion 321c by the dimension z2 shown in FIG. 6 in the z direction. That is, the slit 22 is configured to extend from the upper end (one end) in the z direction of the pouring nozzle 2 to the first part 321 a which is the other side (lower side) in the z direction of the surface 321. In the present embodiment, the first part 321a is located at the bottom of the groove 323. Further, the relative relationship between the dimensions z1 and z2 in the following embodiments is the same as the dimensions z1 and z2 in the present embodiment, but the absolute value may be different for each embodiment.

  The cap 7 is attached to the main body 1 to seal the main body 1 and prevent the contents S from leaking. As shown in FIGS. 1 to 3, in the present embodiment, the cap 7 has a tubular portion 71, a top plate 72, and a cover 73. The cylindrical part 71 is a cylindrical part whose axial direction is the z direction. The tubular portion 71 is located between the pouring nozzle 2 and the wall portion 31 of the liquid receiving portion 3 with the cap 7 attached to the main body portion 1, and the lower end of the tubular portion 71 approaches the surface 321. I have. Further, the upper end of the cylindrical portion 71 is located above the distal end portion 21 of the pouring nozzle 2 in the z direction. The top plate 72 is connected to the upper end of the cylinder 71 in the z direction, and closes the cylinder 71 from above in the z direction. The part constituted by the cylinder part 71 and the top plate part 72 is used, for example, as a part for measuring a predetermined amount of contents S. In this case, the cap 7 is preferably made of a transparent resin or the like. Further, a scale (not shown) used for measurement may be provided on the cylindrical portion 71.

  The cover part 73 is a part that is detachably attached to the wall part 31 of the liquid receiving part 3. The cover part 73 has a mounting part 731 and a connecting part 732. The mounting portion 731 is a cylindrical portion whose axial direction is the z direction, and is mounted outside the wall portion 31. The lower end in the z direction of the mounting portion 731 is close to the connecting portion 62 of the cover 6. The lower end in the z direction of the mounting portion 731 is located above the lower end in the z direction of the cylindrical portion 71 in the z direction. In the illustrated example, a screw portion 733 is formed in the attachment portion 731. The screw portion 733 is screwed with the screw portion 311 of the wall portion 31 and has, for example, a female screw configuration. The connecting portion 732 is an annular portion that connects the upper end of the mounting portion 731 in the z direction and the tubular portion 71. In the illustrated example, a rib 734 is formed in the connecting portion 732. The rib 734 extends downward from the connecting portion 732 in the z direction, and has a circular shape when viewed in the z direction. The rib 734 is provided at a position along the inside of the wall 31.

  As an example of the mode of use of the refilling spout A1, after the pouch container package C1 with the spout is used and the contents S are used up, the refilling spout from the empty pouch container B is used. Stopper A1 is removed. Next, another pouch container B filled with a predetermined amount of the contents S is prepared, and the replacement spout A1 is attached to this pouch container B. That is, the replacement spout A1 is intended to be used repeatedly by being attached to a plurality of different pouch containers B.

  Next, the operation of the replacement spout A1 and the pouch container package C1 with the spout will be described.

  According to the present embodiment, as shown in FIGS. 3, 5, and 6, the wall portion 31 of the liquid receiving portion 3 has a larger diameter than the attachment portion 41 attached to the cylindrical portion 81 of the spout 8. Therefore, it is possible to prevent the cylindrical portion 81 of the spout 8 from having a large diameter while increasing the capacity of the liquid receiving portion 3. The surface 321 has an inclined surface 322, and the lower end 3210 of the surface 321 is located at the position where the slit 22 is located (the first portion 321 a) at the lowest position in the z direction. For this reason, it is possible to guide the contents S received by the liquid receiving part 3 to the slit 22 more reliably, and to prevent the contents S from being unduly left in the liquid receiving part 3. be able to. Therefore, according to the replacement spout A1 and the pouch container package C1 with the spout, it is possible to appropriately receive the contents S remaining in the cap 7 while avoiding an increase in the size of the spout 8. .

  In the present embodiment, since the surface 321 includes the groove 323, the first portion 321a is located at the lowest position in the z direction. In other words, in FIG. 5, the portion located on the right side in the drawing and the portion located on the left side in the drawing in the bottom 32 have substantially the same position in the z direction, and have substantially the same thickness. It is. The main body 1 having such a configuration is suitable for being formed by, for example, die molding.

  The ejection nozzle 2 has a size that overlaps with the insertion portion 42 when viewed in the z direction. For this reason, it is possible to secure a larger space between the pouring nozzle 2 and the wall 31. This is advantageous for increasing the capacity of the liquid receiving section 3.

  The back surface 325 of the liquid receiving portion 3 is parallel to the tip end surface 81a of the cylindrical portion 81, and in the illustrated example, is perpendicular to the z direction. Thereby, the front end surface 81a of the cylindrical portion 81 of the spout 8 can be brought into contact with the back surface 325 over the entire circumference. This is preferable for preventing the contents S from leaking from between the spout 8 of the pouch container B and the main body 1 of the replacement spout A1. Further, since the insertion portion 42 is inserted inside the cylindrical portion 81 of the spout 8, the leakage of the contents S can be more reliably prevented.

  7 to 17 show another embodiment of the present invention. In these drawings, the same or similar elements as those in the above embodiment are denoted by the same reference numerals as those in the above embodiment.

<Second embodiment>
7 to 9 show a pouch container package with a spout according to a second embodiment of the present invention. The pouch container package C2 with a spout according to the present embodiment includes a replacement spout A2 having a configuration different from that of the above-described spout A1.

  The surface 321 of the replacement spout A2 includes the inclined surface 322, but does not include the groove 323 in the above-described embodiment. The surface 321 is parallel to the x direction only at a portion that appears as a part of the cross-sectional view on the right side in FIG. 8, and does not form the inclined surface 322. An inclined surface 322 is formed on the other surface 321.

  The inclined surface 322 of the present embodiment is formed such that the inclination angle increases from the right side in the drawing of FIG. 8 to the left side in the drawing. With such a configuration, also in the present embodiment, the lower end 3210 is inclined such that the azimuth where the slit 22 is located in the circumferential direction is located at the lowest position in the z direction.

  According to the present embodiment as well, it is possible to appropriately receive the contents S remaining in the cap 7 while avoiding an increase in the size of the spout 8. In the present embodiment, it is possible to further increase the inclination angle of the lower end 3210 with respect to the x direction. This is preferable to prevent the contents S from being unduly left in the liquid receiving section 3.

<Third embodiment>
10 to 12 show a pouch container package with a spout according to a third embodiment of the present invention. The pouch container package C3 with a spout according to the present embodiment includes a replacement spout A3 having a configuration different from that of the above-described spouts A1 and A2.

  The pouring nozzle 2 of the replacement pouring plug A3 has a size larger than the insertion portion 42 and located outside the cylindrical portion 81 of the spout 8 in the z direction. In the illustrated example, the pouring nozzle 2 has a size that overlaps with the mounting portion 41 when viewed in the z direction.

  The bottom part 32 of the liquid receiving part 3 has an inner peripheral surface 324 in addition to the surface 321. The front surface 321 is a surface located outside the ejection nozzle 2 when viewed in the z direction, and the inner peripheral surface 324 is a surface located inside the ejection nozzle 2 when viewed in the z direction. The inner peripheral surface 324 has an annular shape when viewed in the z direction. An inner peripheral end of the inner peripheral surface 324 forms a pouring hole 326, and the insertion portion 42 is connected. The inner peripheral surface 324 is inclined such that the inner peripheral surface 324 is located lower in the z direction as going from the pouring nozzle 2 toward the insertion portion 42. The inner peripheral surface 324 has a so-called mortar shape.

  The surface 321 has an inclined surface 322. The portion where the surface 321 is connected to the ejection nozzle 2 is a curved surface that appears in an arc shape in FIGS. 11 and 12. The imaginary line circles shown in FIGS. 11 and 12 are circles formed by the radii R1, R2, and R3 of the curved surfaces of the respective portions for convenience of understanding. As understood from these drawings, the radius R1 of the first portion 321a is smaller than the radius R2 of the second portion 321b and the radius R3 of the third portion 321c. The radius R3 of the third portion 321c is smaller than the radius R2 of the second portion 321b. Between the first part 321a, the second part 321b, and the third part 321c, the radius of the curved surface changes, for example, continuously. By forming such a curved surface, the first portion 321a is located at the lowest position in the z direction among the lower ends 3210.

  In the pouch container B of the present embodiment, a second flange portion 813 is formed on the cylindrical portion 81 of the spout 8. The second flange portion 813 is provided to be spaced apart from the first flange portion 812 downward in the z direction.

  According to the present embodiment as well, it is possible to appropriately receive the contents S remaining in the cap 7 while avoiding an increase in the size of the spout 8. In the present embodiment, the back surface 325 with which the cylindrical portion 81 of the spout 8 contacts is located on the opposite side of the inner peripheral surface 324, and does not overlap with the inclined surface 322 when viewed in the z direction. The portion of the bottom 32 that forms the inclined surface 322 tends to have a relatively inclined shape in order to reliably flow the contents S through the slit 22. If it is attempted to form a back surface 325 perpendicular to the z direction (not inclined with respect to the z direction and the y direction) on the bottom portion 32 having such a shape, a thicker portion is likely to be formed. There is a concern that such a thick portion may be distorted or sinked, for example, when the main body 1 is molded. According to the present embodiment, it is possible to avoid a large inclination of a portion constituting the back surface 325 of the bottom portion 32, and it is possible to suppress an increase in thickness.

<Fourth embodiment>
13 to 15 show a pouch container package with a spout according to a fourth embodiment of the present invention. The pouch container package C4 with a spout according to the present embodiment includes a spout A4 having a different configuration from the spouts A1 to A3 described above.

  In the replacement spout A4, an inclined surface 322 is provided on the entire surface 321 of the liquid receiving part 3. In addition, the lower end 3210 and the upper end 3211 of the inclined surface 322 are inclined so as to be located lower in the z direction as going to the left in the x direction in FIG. 14, and are substantially parallel to each other in the illustrated example. That is, the entire inclined surface 322 having a mortar shape is inclined with respect to the x direction.

  According to the present embodiment as well, it is possible to appropriately receive the contents S remaining in the cap 7 while avoiding an increase in the size of the spout 8. In addition, by inclining the entire inclined surface 322 with respect to the x direction, the contents S in the liquid receiving part 3 can be more reliably guided to the slit 22. As shown in FIG. 14, even though the entire inclined surface 322 is inclined with respect to the x direction, the portion of the bottom 32 that forms the back surface 325 is not inclined with respect to the x direction. This is suitable for forming the back surface 325 which is parallel to the x-direction and the y-direction, and can avoid the occurrence of a portion that is significantly thick.

<Fifth embodiment>
16 and 17 show a pouch container package with a spout according to a fifth embodiment of the present invention. The pouch container package C5 with a spout according to this embodiment is different from the above-described embodiment in that a case D is provided.

  The case D protects the packaging material 9 of the pouch container B, and is attached to the spout 8 in the present embodiment. The material of the case D is not particularly limited, and is made of, for example, a polypropylene resin.

  The shape of the case D is not particularly limited, and in the illustrated example, the case D has a top plate portion d1, a side plate portion d2, and a bottom plate portion d3. The top plate portion d1 is located above the z direction, and has a flat plate shape substantially perpendicular to the z direction. The shape of the top plate portion d1 is not particularly limited, and in this example, is substantially semi-elliptical. Further, a slit d11 is formed in the top plate part d1. The slit d11 has a shape cut in the y-direction, and as shown in FIG. 17, is a portion that holds the cylindrical portion 81 so as to sandwich it from both sides in the x-direction. In the illustrated example, the slit d11 is inserted between the first flange portion 812 and the second flange portion 813 in the z direction.

  The side plate portion d2 is connected to the outer edge of the top plate portion d1, and extends in the z direction. The side plate portion d2 of the present example has a curved surface shape that overlaps the arc-shaped outer edge of the top plate portion d1 when viewed in the z direction. The bottom plate portion d3 is connected to the lower end of the side plate portion d2 in the z direction, and has a flat plate shape substantially perpendicular to the z direction. The shape of the bottom plate portion d3 is not particularly limited, and in this example, is substantially the same as the shape of the top plate portion d1 excluding the slit d11.

  As shown in FIG. 16, the case D has a large opening on one side in the y direction. The case D is put on the pouch container B so that the packaging material 9 of the pouch container B is inserted from the opening. At this time, as described above, the cylindrical portion 81 is made to enter the slit 22, and the slit 22 is inserted between the first flange portion 812 and the second flange portion 813. Thus, the case D is mounted. In the illustrated example, the case where the replacement spout A3 is attached to the pouch container B is shown as an example. However, the present invention is not limited to this, and the replacement spout A1, A2, A4 and the like are included. Various replacement spouts can be used.

  According to the present embodiment as well, it is possible to appropriately receive the contents S remaining in the cap 7 while avoiding an increase in the size of the spout 8. Further, by protecting the packaging material 9 with the case D, it is possible to prevent the packaging material 9 from being broken. The case D can stably stand alone with the bottom plate portion d3 facing down. For this reason, compared with the case where the bottom gusset sheet 93 of the pouch container B is brought into contact with and made independent, the replacement spout A5 can be made to stand more stably. For example, even when the contents S decrease with use and the independence of the pouch container B alone becomes unstable, by attaching the case D, the dispensing spout A5 is surely made independent. Can be done.

  The replacement spout and the pouch container package with the spout according to the present invention are not limited to the embodiments described above. The specific configuration of each part of the replacement spout and the pouch container package with the spout according to the present invention can be variously changed in design.
